General Description

The HMC425LP3 & HMC425LP3E are broadband

6-bit GaAs IC digital attenuators in low cost leadless

surface mount packages. Covering 2.2 to 8.0 GHz,

the insertion loss is less then 3.8 dB typical. The

attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and

16 dB for a total attenuation of 31.5 dB. Attenuation

accuracy is excellent at

0.5 dB typical step error

with an IIP3 of +40 dBm. Six control voltage inputs,

toggled between 0 and +3 to +5V, are used to select

each attenuation state. A single Vdd bias of +3 to +5V

is required.
